Mechanical Properties of the Cracked Thick Aluminum Plate Repaired with M4OJ/Epoxy Composite Patch
To extend the service life of the equipment, a novel, efficient and cost-effective method is used to recover the damaged component of the equipment.The mechanical properties of unidirectional M40J/epoxy composites, prepared by molding process, were studied.Then the centre-cracked thick LC52CS aluminum plates were single and double side repaired with the composites patches by vacuum bagging technology in which three cure cycles were applied.Results show that a low cure temperature induce a small thermal residual stress, Choosing the cure cycle with the highest tensile strength of single-side repaired specimens, the tensile strength of single-side and double-side repaired specimens enhance 31.50% and 47.29% of that of the unrepaired specimens, respectively.And fatigue life of the double-side repaired specimens extends that of the cracked aluminum plate over 76 times, which is also significantly better than that of the single-side repaired specimen.
